The chemical compound "(20Ξ)-9-fluoro-2-hydroxymethylene-17,20;20,21-bis-methanediyldioxy-16α-methyl-pregn-4-ene-3,11-dione" is a complex steroidal molecule with a unique structure. It features a pregnane core, which is a type of steroid, with a 4-ene-3,11-dione functional group, indicating the presence of a double bond at the 4th position and a ketone group at both the 3rd and 11th positions. The molecule also includes a 9-fluoro substitution, which introduces a fluorine atom at the 9th position, and a 2-hydroxymethylene group, which adds a hydroxymethylidene moiety at the 2nd position. Additionally, it has a 16α-methyl group, which is a methyl group attached to the 16th carbon in the α-configuration. The compound is further characterized by two methanediyl groups that form a dioxolane ring at the 17,20;20,21 positions, which are part of the molecule's oxygen-containing ring structures. (20Ξ)-9-fluoro-2-hydroxymethylene-17,20;20,21-bis-methanediyldioxy-16α-methyl-pregn-4-ene-3,11-dione is likely to have specific biological activities due to its structural features, which are common in pharmaceuticals and other bioactive molecules.

2559-23-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2559-23-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,5 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.Calculate Digit Verification of CAS Registry Number 2559-23:
(6*2)+(5*5)+(4*5)+(3*9)+(2*2)+(1*3)=91
91 % 10 = 1
So 2559-23-1 is a valid CAS Registry Number.
